The first stage of Saturn V was to be the launch stage of 10 m Orion. It's no need to lift it to LEO by rocket. If Nerva was in active use before the Orion-scale orbital operations, which looks doubtful. Probably they would be complementing each other.

Any engine was originally never used yet. Also, is it Spaceflight & Science or KSP Questions part of the forum? The game logic differs from the real world one. You can't use ше at low altitudes. But you can do it in thin air, where the shockwaves and secondary radiation are negligible. So, lift it up to 50..60 km where the conditions don't differ from vacuum until you reach 8 km/s speed, and start nuking. They are absolutely negligible for low-kiloton yield at hight altitude, with pure-uranium charges, several times per year. What's the difference between 1 000 t of nuke and 1 000 t of sand? In kitchen - yes. But the nuke connstructors were sure that's not a big deal, and there is no visible reason why not. Anyway, I took the Sundial as a reference point for the ship mass, so I can't see why do you focus on the Sundial details when the talk is about Orion. The liquid deuterium is the worst possible fusion fuel in sense of energy-to-mass ratio. The combat version of that 82 t Ivy Mike charge (aka EC-16/TX-16) was weighting 19 t, yield ~10 Mt so its ratio was 0.5 Mt/t. This is by order of magnitude worse than was achieved by the LiD bombs. Even if take the deuterium spatial density in LiD, it's 2/8*820 ~= 200 kg/m3, when the liquid deuterium is ~220. And the litium is weighting definitely much less than required heavy metals. As the theoretical upper limit of the yield-to-mass ratio is ~80 kt/kg for D,DT and ~50 kt/kg for LiD, this also means that deuterium is at least twice worse in sense of energy-per-voulme. So, the only reason to mention the liquid deuterium at all is a historical one. The fusion reactions were discovered in early 1930s, earlier than spontaneous fission, and the nukes were originally seen as fusionukes, just nobody had an idea neither how to ignite, nor where to take tritium. So, they were hoping on liquid deuterium and doubted in LiD until its first tests, The "classic Super design" included all possible designs in different variants. It's just a colloquial term for the early idea of a thermonuke. I've heard about the electromagnetic force, the weak and strong forces, and even the gravitational one. But what is "brute force" to be just applied? Something different from these four ones? If just put a primary next to the secondary, you will get a cloud of dispersed secondary. Only negligible part of it will have time to react. If put it inside, the cloud will be spherical. You anyway have to oppose the overheated fuel expansion, and it's inertial confinement. You need either heavy metal rock inertia, or thick layer of non-reacted fusion fuel. So, in any case only small part of total mass will react. Gigaton? Not teraton? Not petaton? What makes to think so? I can neither connect these two theses, nor reailize what are those specific complexities when there have been tested multimegaton charges. Ion engines are either low-thrust or low-efficiency. They are for tiny actions. Nerva and Orion have absolutely different principles and different range of thrust. Nerva is 40 tf and 9 km/s of ISPg, Orion is from 100 to many thousands tf and ~100 km/s of ISPg. Their construction don't follow each other, so they are on independent branches of Tech Tree, just Nerva is simpler to build, that's why it historically appeared sooner. Orion depends not on nuke reactor progress, but on pneumatics and mechanics for its piston thing. So, it more depends on big combustion engines rather than Nerva. Easily and precisely throttlable as irl anyway would be DT-boosted. So, you can throttle it just by limiting the amount of tritium in the boosting gas, total 1.5 g or just 0.783 g, or maybe 0.045 g. In game parts, not irl parts.

Teller said this not about SUNDIAL, but about the post-B41 bomb. Assemble a thousand-ton heavy charge in space? When its charge would weight several hundred ton alone? Even not funny. Especially since such assembly would be likely stopped by an opponent nuke in process. Sundial is to be launched in one piece secretly, unless it would be intercepted, and very probably right on the launchpad. We know definitely that no planned chemical rocket could lift thousand(s) tonnes. Even the Nexus versuion with gaseous nuclear engine on the upper stage. Orion is the only option, and it's mentioned. So, it's useful as an example of the Orion ship. Also it matches the known Orion mass range, and its 23 m diameter matches the Nexus and Dragon, so is useful as an estimation example. Deuterium efficiency was 15/82 Mt/t last time when it was tested, and it was replaced with LiD as soon as possible (in two years) exactly due to its extremely poor energy-to-mass ratio. The Teller-Ulam scheme is doing this as well, just it's based on cylindric implosion. And exactly to improve the ratio, Teller himself mentioned the spherical implosion. The specifics of the deuterium test is well-known. And the last T-U scheme charges have been dismissed decades ago. And in any case, you need a heavy casing to absorb X-ray and heat the heavy shell to compress the fusion core, so the fusion fuel will take much less than 100% of the charge mass.

4 000 000 kg ship * 10 m/s2 * 150 000 m/s ISP = 6*1012 W. Orion looks weird until you imagine a ~10 TW reactor with ~10 TW radiator panels, and compare which one looks more realistic.

Granted. Now you receive every signal twice. I wish to know what do the people on that bus stop think about.

Calling 911 because the already orbiting starlinks have shaded you from the Sun, so you think it's eternal night.

We can name the Earth poles after him.
